Hi People, have a problem with my 1997 S280, owned the car for 2 years now and its the 1st prob.
car starts and runs fine at first, but on a long trip after cruising a while it lacks power and the engine develops a miss at idle.
Ive noticed a huming like noise that I dont think was their before, if you turn on ignition (Dont start engine) from under the fuel manifold.
Its Irish(As am I) R.H.D. and its just been fully serviced (Prob was there before service) but the problem persists.

Any Ideas?

Thanks

Alan.
